Srilankan Airlines Flight cancellation and refund request

Sir/Madam
This is with regards to my mom named SABIHA ANSURUDEEN aged 70 years had a flight travel on 23rd Nov through Srilankan Airlines from Madurai to Riyadh via Colombo, with BOOKING RESERVATION NO 6MQMYX.
The ticket was booked on 17th Nov 2022 itself, with a plan that she will accompany another person (my Friend) who was also travelling from Madurai to Riyadh in the same flight, so we planned to travel from our home town Coimbatore to Madurai by taxi. Upon reaching the airport on 23rd and my mom got her security and immigration done as usual, being aged and with travel earlier she was made to wait for flight delay, the flight authorities did not inform regarding the delay.
My mom got all her immigration and security check and waiting for boarding, we were informed about the cancellation half an hour to 40 miniutes after the scheduled departure time, They did not give any proper reason and said its technical fault,
The airlines authorities had not offered her any consolation by asking her to stay in hotel which was obligation of the airlines to book hotel till the next schedule flight. She was left to wander without any help from the authorities, till late night. Until taxi was booked by us for her.
The airlines gave an option for another flight after two days, Which was not viable in her aged days to travel again from Coimbatore to Madurai again affecting her health.
As mentioned, she had come from far of place from Coimbatore around 236 KM with 5 hour travel time via road and we had spent for her local travel and she had to book another taxi to go back home again due to cancellation .
We have incurred lot of expenses for my travel to and fro, . Also she had to undergo health issues and had to led to lot of stress.
Also since she had to travel urgently, we booked from an alternative flight on Friday from Cochin
I would like compensation for the cancellation and the stress she had undergone and the financial expense we took because of this uninformed cancellation. Which is totally under Airlines responsibility
